Materials Management

Ammonia should be stored in a cool, dry, well-ventilated area and in tightly sealed containers protected from exposure to weather, extreme temperature changes, and physical damage. It should be separated from oxidizers, combustible materials, heat, sparks, and open flame. As a liquefied gas, ammonia is flammable. Sources of ignition usually include smoking or open flames. Ammonia is considered a strong oxidizer, and steps should be taken to separate ammonia and ammonia products from incompatible materials such as copper, brass, bronze, galvanized steel, tin, or zinc (10).
